I lost about 80 pounds 9 years ago. 65 of that was within 6 months, and the last 15 was kind of a one off thing during an incredibly strenuous camp that I was medical counsel for; after I finished this camp, I actually would fall asleep whenever I would eat food for about 2 weeks.
I gained it back slowly between 2016 to now. I've been pretty steady at the current weight, but I'm much fitter than I used to be [currently not as I have just had a crazy ass bout with an illness and then surgery following the illness - I'm only now allowed to exercise again].
I can't say I ever ate the healthiest, but I would have a vegetable stir fry alternating with a shrimp stir fry each week, sometimes both in the same week, and then I would alternate healthy and unhealthy meals. I essentially stopped eating fried foods and breads during this time period. I would get about 2 15 minute walks in in the morning and afternoon, and then an hour long walk in the evenings most days out of the week. I would usually eat out once a week. I also would work in swimming and weight lifting 2-3 times per week. On weekends I would go hiking, and in the winter I would ski.
Sometime around 2016 I started to have an absolute aversion to my vegetable stir fry and my shrimp stir fry. I have gotten better about enjoying my vegetable stir fry, but the shrimp stir fry has been hard to surmount. At my workplace people just bring me food, and that's hard to avoid; I also get free lunch twice a week. I am somewhat selective about my lunch choices now.
Part of my troubles with food include:
Clif Bars: These are candy bars disguised as energy bars, because they are energy bars, but they taste like delicious. They're a wonderful replacement meal when you're doing a 10 mile hike, but they're dangerous to have around the house immediately after getting home from work, or immediately after dinner.
Trail Mix: I've never taken trail mix.. on the trail. I've had to just stop buying this, and I buy honey roasted cashews instead, which I do not snack on as hard.
Yerba Mate: I got into a bad habit of relying on these for caffeine. They have about 120 calories each, and are delicious. I went for a decade without any liquid calories outside of almond milk, and occasionally regular milk. I have remedied this by buying some incredible loose leaf chocolate mate and a portable tea strainer for work.
What I do right:
I am a very active person. Since late August I have been forced to not exercise, and I have really struggled with it. I can exercise now, but I am having to shift my routine to the morning because my nether region gets sore nightly because of fluid shifting lower due to my surgery. Part of being an active person is also what I do wrong; it drives my hunger and eating habits.
What I think hurts me:
My friend circle has largely dissipated into their own little nuclear families. I think I am prone to eating if I am not around friends enough. I know that sounds corny. My best friend might be moving back soon, but it's so expensive here that I'm not sure he'll be happy with what he can afford.
